If you were ever attacked by a grizzly and survived, you are one of the lucky few.

He attributes to why he survived to something you may not expect. You see, during the midst of the attack, he remembered something that, at his grandma’s urging, he read in a magazine about shoving his arm down the grizzly’s throat.

Luckily for him, it worked.

Chase Dellwo was walking a ridge with his brother during an archery elk hunt in Montana. They spotted some elk and split up, according to their game plan, to get a shot. As Dellwo was walking his path to circle the elk, he walked right into a sleeping grizzly.

“I had an arrow nocked, and I put my bow up in front of me and took two or three steps back,” Dellwo said. “There wasn’t any time to draw my bow back.”
